Description

Verfahren zur ununterbrochenen Herstellung von Lösungen gleichmäßiger Dichte.Method of continuously making solutions more uniform Density.

Der Erfindungsgegenstand unterscheidet sich von den bisher bekannten Verfahren zur ununterbrochenen Herstellung von Lösungen gleichmäßiger Dichte dadurch, daß die der Zuführungsrinne eng, trömende Lösungsmittelmenge durch eine drehbare Scheidewand in zwei Teile zerlegt wird, von denen der eine einer Sättigungsvorrichtung zufließt und aus dieser eine-gleiche Menge gesättigter Mutterlösung verdrängt, die durch den übrigen Teil der Flüssigkeit verdünnt wird, wobei ohne Änderung der Menge des zuströmenden Lösungsmittels durch eine einfache Drehung der Scheidewand Mischlösungen von beliebigem Verdünnungsgrad hergestellt werden können. The subject of the invention differs from the previously known Process for the continuous preparation of solutions of uniform density by that the supply chute narrow, flowing amount of solvent through a rotatable The septum is disassembled into two parts, one of which is a saturation device flows in and displaces an equal amount of saturated mother liquor from this is diluted by the remaining part of the liquid, without changing the amount of the incoming solvent mixed solutions by simply turning the partition of any degree of dilution can be produced.

Mittels einer von dem spezifischen Gewicht der Mischungslösung abhängig gemachten Regelungsvorrichtung kann der Erfindungsgegenstand so ausgebildet werden, daß die Dichte der Mischung auch bei einer Änderung des Sättigungsgrades der Mutterlösung selbsttätig gleichbleibend gehalten wird.By means of a depending on the specific weight of the mixture solution made control device, the subject matter of the invention can be designed in such a way that that the density of the mixture also with a change in the degree of saturation of the mother liquor is automatically kept constant.

Auf der Zeichnung ist der Erfindungsgegenstand dargestellt. Die Zuführung des Lösungsmittels Q erfolgt durch eine rechteckige Ausflußöffnung a, unterhalb deren sich der Doppeltrichter b, c befindet. Der Trichter b nimmt die Flüssigkeitsmenge q1, der Trichter c die Menge q2 auf. Die Scheidewand d zwischen den beiden Trichtern ist drehbar ausgebildet, sie soll im nachfolgenden als Regelungsklappe bezeichnet werden. Ihre Oberkante, die zweckmäßig angeschärft wird, zerlegt den Flüssigkeitsstrahl und damit die Menge Q in zwei beliebige Teile kl und q2. Aus dem Trichter b gelangt das Lösungsmittel in den Sättiger e, welcher bei f mit dem Lösungsgut beschickt wird, und dessen tiefstem Punkte die Mutterlösung mittels des Steigrohres g entnommen und von hier in den Mischtrichter h befördert wird. Aus dem Trichter c fließt die Menge q2 des Lösungsmittels unverändert ebenfalls in den Mischtrichter h, wo sie sich mit der verdrängten Mutterlösung zu einer Mischlösung vereinigt. Durch eine Drehung der Regulierklappe d nach rechts oder links kann das Verhältnis ql : q2 ohne Änderung von Q vergrößert oder verkleinert werden, so daß bei gleichbleibender Dichte der Mutterlösung jeder Stellung der Klappe ein bestimmter Verdünnungsgrad der Mischlösung entspricht. The subject of the invention is shown in the drawing. The feed the solvent Q takes place through a rectangular outlet opening a, below which is the double funnel b, c. The funnel b takes the amount of liquid q1, the funnel c the quantity q2. The partition d between the two funnels is designed to be rotatable; in the following it will be referred to as the control flap will. Their upper edge, which is appropriately sharpened, breaks up the jet of liquid and thus the set Q into two arbitrary parts kl and q2. Comes out of the funnel b the solvent in the saturator e, which is charged with the solute at f is, and the lowest point of which the mother solution is removed by means of the riser pipe g and from here it is conveyed into the mixing hopper h. The flows out of the funnel c Quantity q2 of the solvent also unchanged in the mixing funnel h, where they combines with the displaced mother solution to form a mixed solution. By a Turning the regulating flap d to the right or left can result in the ratio ql: q2 can be increased or decreased without changing Q, so that while remaining the same Density of the mother liquor each position of the valve a certain degree of dilution corresponds to the mixed solution.

Tatsächlich ist nun der Sättigungsgrad der Mutterlösung nicht gleichbleibend, sondern ändert sich mit der Temperatur; zur Erzielung einer gleichmäßig dichten Mischlösung ist daher erforderlich, entweder die Temperatur gleichbleibend zu halten oder die Sättigungsschwankungen der Mutterlösung durch entsprechende Einstellungen der Regelungsklappe auszugleichen. Denn eine Veränderung der Zufiußmenge Q läßt das Verhältnis q1: q2 unberiihrt,-da die Breite des Flüssigkeitsstromes, welche durch die Regelungsklappe nach dem angegebenen Verhältnis zerteilt wird, unverändert bleibt.In fact, the degree of saturation of the mother solution is not constant, but changes with temperature; to achieve an evenly dense Mixed solution is therefore necessary either to keep the temperature constant or the saturation fluctuations of the mother solution through appropriate settings to compensate for the control flap. Because a change in the inflow quantity Q can the ratio q1: q2 is not affected, since the width of the liquid flow, which is divided by the control flap according to the specified ratio, unchanged remain.

Es erscheint nun wünschenswert, die winstellung der Regelungsklappe selbsttätig erfolgen zu laSsen, indem die Klappenstellung in ein zwangläufiges Abhängigkeitsverhältnis von der Dichte der ischlösung gebracht wird. It now seems desirable to adjust the control flap to be done automatically by placing the flap position in an inevitable dependency relationship is brought about by the density of the solution.

Dies kann in folgender auf der Zeichnung dargestellten Weise geschehen: Der Behälter i, dem die verdünnte Lösung zufließt, ist mit einem b'berlauf,i versehen, welcher den Flüssigkeitsspiegel auf gleichbleibender Höhe hält. In dem Gefäß i befindet sich ein Schwimmkörper 1, der durch ein Gestänge m, 1 mit der Regelungsklappe in Verbindung steht, so daß bei einem Steigen der Dichte der Mischlösung der Schwimmer ebenfalls steigt, wodurch die Klappenstellung derart beeinflußt wird, daß das Verhältnis q1: q2 und damit die Dichte der Mischlösung sich verringert, während bei sinkender Dichte der Mischlösung das Umgekehrte eintritt.This can be done in the following way shown in the drawing: Of the Container i, to which the diluted solution flows, is provided with an overflow, i, which keeps the liquid level at a constant level. In the vessel i is located a float 1, which is connected by a linkage m, 1 with the control flap in Is connected so that when the density of the mixed solution increases, the float also increases, whereby the flap position is influenced in such a way that the ratio q1: q2 and thus the density of the mixed solution decreases, while with decreasing Density of the mixed solution the reverse occurs.
